The National Police Gazette, commonly referred to as simply the Police Gazette, was an American magazine founded in 1845 by two journalists, Enoch E. Camp, also an attorney, and George Wilkes, a transcontinental railroad booster. In 1866, Wilkes and Camp sold the Gazette to George W. Matsell. The editor and proprietor from 1877 until his death in 1922 was Richard Kyle Fox, an immigrant from Ireland.
Ostensibly devoted to matters of interest to the police, it is a tabloid-like publication, with lurid coverage of murders, Wild West outlaws, and sport. It is well known for its engravings and photographs of scantily clad strippers, burlesque dancers, and prostitutes, often skirting on the edge of what is legally considered obscenity.
The National Police Gazette enjoyed considerable popularity in the late 19th century and early decades of the 20th century; but its popularity decreased during the Great Depression. The National Police Gazette continued on after the death of Fox as a monthly publication for many years before ceasing print publication in 1977.
In its heyday it was immensely influential. In the first part of the 20th century, the United States became the centre for professional boxing. It was generally accepted that the "world champions" were those listed by the Police Gazette. After 1920, the National Boxing Association began to sanction "title fights". (Source: wikipedia)
